Inadequate industrial base of specially skilled workers and industries- such as engine manufacture. Possible environmental concerns. It is interesting to note that Greece has never produced any aircraft of note. They use American made transports for the Olympic Airways- an Onassis company.
Helicopters can land where airplanes cannot.
Some airplanes are made in the US, but not all. there are several other countries int he World that can make airplanes too.
enginners build rockets, airplanes, ect.
Electric remote control airplanes are difficult to build if you do not have step by step directions or at least some previous hobby building experience. The more practice, the more efficient you will become at building.
No. All airplanes can't carry weapons but some airplanes can carry weapons. If it is a military aircraft so yes they can carry weapons but if it is a friendly aircraft so no they cannot carry weapons.
Yes, jets are airplanes but they are called supersonic airplanes.
no in some countries they cannot.
The Eyjafjallajökulls erupted first in mars the 20 2010. Laterthe volcano erupted again and this made it hard for some countries such as Norway and other North Europa countries to take airplanes
They both (some airplanes do) use propeller's.
Answer There are basically three types of airplanes. Wood and fabric. The earliest airplanes were constructed with wood frame covered in fabric that was glued in place. There are people who still have this skill to build airplanes like this. Metal- aluminum - Modern planes are built with aluminum frames that have a monocoque skin stretched over it and held in place with rivets. Steel is used for some structure and application. Composite - Airplanes are now being made of composite material such as fiber-glass or derivatives of carbon and glass fibers. These can be made using a mold that gives the fuselage and wings their shape. If you build an airplane, you require a license by the FAA. There are some that you can build under the supervision of a qualified mechanic. The rules are there to prevent you from hurting people when you crash.
Yes, airplanes can carry weapons. That's quite true that some airplanes can really carry weapons.
Two companies currently build WW1 reproductions. Airdrome Aeroplanes in Holden MO builds 3/4 scale fully working airplanes. These planes are flighable. Vintage Aviator in NZ also builds reproductions. They have some incredible videos of their airplanes being built. Worth taking a look at.
